For the sine wave is the fundemental of all sounds.
It's very ok.
i think they call can be.... what can not?
duh... its like saying circles are round..
circles are round!
Every sound can be broken down into finite combinations of sine waves.
i speak only in tangent waves......
That would be, 'fundamental.'
yea in your topic, you said "almost any" so i was wondering if there was some special one i didn't know about.
but yes, it's very cool.
sine sweeps on subs = teh win

Because we know your cheap ass sound card is the best technology has to offer.
Better pay more attention in class.
white noise, blue noise, pink noise, and brown noise would be pretty hard to make since they are completely random in nature and there are no mathematical formulas that produce truly random numbers.
i am unfamiliar with blue noise, please explain...

Textbook definition: In a spectrum of frequencies, a region in which the spectral density, i.e. , power per hertz, is proportional to the frequency.
not necessarily a finite number...it's called fourier theory and it applys to any function, not just a sound wave.
the individual sine waves are plotted in the top box...their amplitudes obtained by calculating the fourier transform of the dashed box function. The lower box is the sum of all the sines in the upper box...notice how close we come to getting a square wave after only 200 summed together.
this off center box does not share any of the symmetries of sine waves. If we can do this good a job making up this function, it seems plausible that we can make pretty much any shape we like by adding sines and cosines together.
hmm... good point. are those types of noise natural? if so, where are they produced.
Go to the toy store and find a toy that quacks.
elephants are decently large animals. if one steps on you, it will most likely hurt.
It's sorta natural. Turn your radio to an off-air station and you'll hear white noise. It's pretty much a reflection of your enviroment.
